55% of 120 is just 66
add that with 120, 186
so... 186 books
5w^2 = A
You would multiply the width (w) by 5 because it's 5 times more than twice it's width. Then w (Width) would be to the power of 2 because it's 5 times more than twice its width. And this will all equal the Area (a)
Answer:
32 5/8 (or 32 and 5/8)
Step-by-step explanation:
Okay, so this problem is asking for us to solve this problem with the substitution of a variable: x = -4. Before we fully solve this problem, we need to replace all of those x variables with -4 so that it is easier to solve.
-7 1/4(-4) + 3 5/8.
To make this problem even easier to solve, let's turn these mixed numbers into improper fractions. To do this, multiply the denominator by the whole number. Then add the numerator to this number. The new number that you just got is now your new numerator for this number.
-29/4(-4) + 3 5/8.
Repeat the last step to turn the other mixed number into an improper fraction.
-29/4(-4) + 29/8.
Now let's multiply that -4 by 29/4. Because a whole number technically has a denominator of 1, we can now set up the next part of our problem. (The symbol * means multiplication since we can't use x since it is already being used as a variable in this equation.)
(-29/4 * -4/1) + 29/8.
29 + 29/8.
Now to solve the rest of this problem, let's convert the whole number of 29 so that it has a denominator of 8. This is that these two numbers are addable.
<u>29</u> x <u>8</u> = <u>232</u>
1 x 8 = 8
Now these numbers are addable. So:
232/8 + 29/8 = 261/8 = 32 5/8.
I hope that this helps.
Answer:
Step-by-step explanation:
Given that 
is a right angled triangle.
and
Kindly refer to the attached image of in which all the given angles are shown.
To find:
sin(38°) = ?
a) cos(38°)
b) cos(52°)
c) tan(38°)
d) tan(52°)
Solution:
Let us use the trigonometric identities in the given .
We have to find the value of sin(38°).
We know that sine trigonometric identity is given as:
....... (1)
Now, let us find out the values of trigonometric functions given in options one by one:
....... (2)
By (1) and (2):
sin(38°) 
cos(38°).
...... (3)
Comparing equations (1) and (3):
we get the both are same.
F=95(K−273.15)+32
Switch the equation so that F is on the right side:
95(K−273.15)+32 = F
Use the distributive property:
95K + 95(-273.15) + 32 = F
95K - 25949.25 + 32 = F
95K - 25917.25 = F
Add 25917.25 to both sides:
95K = 25917.25 + F
Divide each term by 95:
K = 25917.25 / 95 + F/95
K = (25917.25 + F) /95
